EFFECTIVE DOSES AND RADIATION RISKS FROM COMMON DENTAL RADIOGRAPHIC, PANORAMIC AND CBCT EXAMINATIONS

Abstract

Abstract This study was aimed at the estimation of the effective doses and radiation risks from dental X-ray examinations based on the data collection in St. Petersburg and the Leningrad Region. The range of mean values of effective doses for intraoral examinations on the X-ray units with film detectors was from 3.5 to 8.2 μSv and for the units with digital detectors—from 1.2 to 2.5 μSv. The mean effective doses for panoramic examinations were 22.9 μSv and for cone-beam computed tomography (CBCT)—530.6 μSv, respectively. The highest detriment-adjusted lifetime risk values were estimated for the 20–24-year-old age group: 40.8 × 10−6 in females and 32.7 × 10−6 in males for CBCT. Effective doses in St. Petersburg and Leningrad region were comparable or higher compared with the published data.
